 * VM Testbase readme:
 * DESCRIPTION
 *     This JVMTI test exercises JVMTI thread function GetCurrentThreadCpuTimerInfo().
 *     This test checks that GetCurrentThreadCpuTimerInfo() returns info structure
 *     with correct values and produce no errors. And these values are not
 *     changed between calls.
 *     The following checks are performed for GetCurrentThreadCpuTimerInfo():
 *         - in VM_INIT event callback on live phase
 *         - in agent thread on live phase
 *         - in THREAD_START event callback on live phase
 *         - in THREAD_END event callback on live phase
 *         - in VM_DEATH callback on live phase
 *     Each check passes if GetCurrentThreadCpuTimerInfo() returns not negative
 *     or zero value in max_value field, and values of all fields are equal to
 *     initial values.
 *     Debuggee class runs special tested thread to generate THREAD_START
 *     and THREAD_END events.
 *     If all checks are successful, then test pases with exit status 95.
 *     If any check fails or other error occurs, then agent sets FAIL status
 *     and the test fails with exit status 97.
 *     If the last check (in VM_DEATH callback) fails, then C-language exit()
 *     function is used to force VM exit with fail status 97.
 * COMMENTS
 *     Fixed the 5006885 bug.
